Challenge #1

Can you draw bubbles floating to the sun?

Did you know: Bubbles aren’t usually thought of as weapons, but that is exactly how the snapping shrimp uses them. They create a cavitation bubble that immediately collapses creating a shock wave that, for a moment, is nearly as hot as the sun.

Challenge #3

Can you draw square bubbles?

Did you know: Bubbles are round because, just like balloons, they are what scientists call ‘minimal surface structures’. What this means is that bubbles hold the air enclosed inside them in the least possible surface area that they can. Out of all the geometric shapes such as cubes, or pyramids, the geometric form with the least surface area is a round sphere! So sadly, it isn’t possible to make square-shaped bubbles.
